Purification Methods
Crystallise lanatoside B from MeOH. Its solubility is: 1/20 (MeOH), 1/40 (EtOH), 1/5600 (CHCl3), and is insoluble in H2O. [Stoll et al. Helv Chim Acta 16 1049 1933, Miyatake et al. Chem Pharm Bull Jpn 5 171 1957, Beilstein 18 III/IV 2465.] It is cardiotonic.
Check Digit Verification of cas no
The CAS Registry Mumber 17575-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,7 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17575-21:
(7*1)+(6*7)+(5*5)+(4*7)+(3*5)+(2*2)+(1*1)=122
122 % 10 = 2
So 17575-21-2 is a valid CAS Registry Number.
